Followed your suggested change, it might work for the Junit test case, but it failed with the "ordinary" case: | calling_card_reg # ant test | Buildfile: build.xml | | compile-test: | [javac] Compiling 11 source files | [javac] /usr/liferay-portal-5.2.3/dev/portlets/calling_card_reg/docroot/WEB-INF/src/com/ip6networks/calling_card_registration/struts/action/CallingCardRegistrationAction.java:29: package com.liferay.portal.struts does not exist | [javac] import com.liferay.portal.struts.PortletAction; | [javac] ^ | [javac] /usr/liferay-portal-5.2.3/dev/portlets/calling_card_reg/docroot/WEB-INF/src/com/ip6networks/calling_card_registration/struts/action/CallingCardRegistrationAction.java:34: package javax.portlet does not exist | [javac] import javax.portlet.ActionRequest; | However I don't expect running "ant test" will caused the code above to be compiled. How to "exclude" the compilation only goes to "com.ip6networks.calling_card_registration.test" rather than "com.ip6networks.calling_card_registration.Action" ? Thanks very much for patient.
